PETERSON, E LELAND, IOWA ANTICLOGGING DEVICE FOR CORN PICKERS Application filed. December 9, 1929. Serial No. 412,789.

The principal object of my invention is to corn pickers as will be appreciated by those provide a device used in combination with familiar with the art. a corn picker that eliminates the tendency of I have used the numerals and 11 to desigcorn pickers to clog up with cornstalk and nate the two spaced apart shoes and guiding 5 cars at the upper ends of the snapping rolls shields of the common and well known corn thereby making the corn picker more eiiipickers. Below each of the shields is a cient and eliminating the danger of injury snapping roll, which I have designatedby the to the operator in manually clearing the numerals 12 and 13.

I have overcome this objection in betWeenthe snapping rolls and as the rotation of the disk 19 is downwardly and toward the snapping roll 13, the disk 19 and cutting blades 21 will not only cut ofi any cornstalks and ears that have clogged at the rear end of the snapping rolls but will guide and move the material so cut into and onto the elevator chute of the corn picker thereby eliminating any possibility of a clogged condition at the rear end of the snapping rolls.

The numeral 22 designates a second sprocket wheel rigidly secured to one of the upper sprocket wheels 32, as shown in Fig. 1

On the Outer end of the shaft 17 I have secured the bevel gear 23. The numeral 24 designates a second bearing member secured to the corn picker rotatably mounted in which is the short shaft 25. Secured on one end of the shaft 25 is the bevel gear 26 and secured on its other end is the sprocket wheel 27. Embracing the sprocket wheel 27 and the drive sprocket wheel 22 is the endless chain 28.

I have used the numeral 30 to illustrate a tract-ion wheel which is operatively connected to the rotatably mounted shaft 31 of the corn picker. This is accomplished by a shaft 32 rotatably mounted on the corn picker having a bevel gear 34 in operative engagement with the bevel gear 35 on the traction wheel shaft 36. The numeral 37 designates a sprocket gear on the shaft 32 and the numeral 38 designates a similar sprocket gear on the shaft 31. The numeral 39 designates an endless chain embracing the sprocket gears 37 and 38. Rigidly secured on the shaft 31 is a worm gear 40 in engagement with the rotatably mounted gear 41 which is also in engagement with the chain 14, as shown in Fig. 1. By this arrangement when the corn picker is being pulled over the ground the traction wheel 30 will be operatively connected to the endless chain shown in Fig. 1 and as this endless chain is operatively connected to the sprocket gear 22, the disk 19 will be rotating in the proper direction for the clearing of the corn picker of undesirable congestions.

Vith the installation of my invention a corn picker will function continuously in any type of corn without undesirable clogging at the rear ends of the snapping rolls thereby eliminating waste of corn, time and labor, as

well as eliminating the possibility of injury to the operator in attempting to clear stoppages with his hands or feet.

Some changes may be made in the construction and arrangement of my improved combination anti-clogging device for corn pickers without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope. 1

I claim:

1. In combination with a corn picker having snapping rolls, a disk rotatably mounted above the snapping rolls and cutting a path across the space between said snapping rolls for clearing the same of clogged material, and a means for operatively connecting said disk to the traction power wheel of said corn picker.

2. In combination with a corn picker having snapping rolls, a concave disk rotatably mounted above said snapping rolls and cutting a path across the space between said snapping rolls, and gears for operatively connecting said disk to the operating power of said corn picker.

3. In combination with a corn picker having snapping rolls, a disk rotatably mounted above said snapping rolls, a means for operatively connecting said disk with the operating power of said corn picker, and a plurality of cutting blades secured to said disk.

1. In combination with a corn picker having snapping rolls, a disk rotatably mounted above said snapping rolls, a means for operatively connecting said disk with the operating power of said corn picker, and a plurality of curved cutting blades secured to said disk.

5. In combination with a corn picker having snapping rolls, a concave disk rotatably mounted above the rear end portions of said snapping rolls, and so positioned as to cut a path from a point above the outside snapping roll to a point above the inside snappingroll. curved blades secured to the concave side of said disk, and a means for rotating said disk when said corn picker is in operation.

CHRIST H. PETERSON.
